Bibliographic records describe items (books, serials, DVDs, e-resources, maps, software, etc.) owned by the Libraries. They generally provide information about authors, titles, publication dates, subject headings, and call numbers. For detailed information on how libraries represent these descriptive fields, click “Staff View” within the catalog’s listing of an item. Each number represents controlled and searchable information. For example, the main author is 100, the title is 245, a subject heading is 650, and the call number is either 090 or 050. Coding the numbers and descriptive data in a precise configuration is essential for the data to appear in the online catalog.
